Renowned instructor and Renzo Gracie Black Belt, Karel “Silver Fox” Pravec presents a unique submission focused approach to Brazilian Jiu Jitsu geared towards the less athletically gifted practitioner.

Every technique and drill in this series is applicable to all skill levels, sizes and ages.

Master Renzo Gracie

“One must never be entirely comfortable at what he has achieved. This is the truth behind every great Jiu-Jitsu teacher… Karel Pravec is always improving his game and his knowledge of the art… He knows that to do otherwise is to settle. I salute you my fellow Black Belt. Excellence among us, it’s a must… Our students deserve the best of us. Thank you for belonging to our tribe.
Fernando Pessoa, a great Brazilian writer once said … “The value of things is not the time they last, but the intensity with which they occur. That is why there are unforgettable moments and unique people!”
Karel Pravec is among those unique people; lucky are those who learn under his tutelage.”

Master Renzo Gracie – 6th degree BJJ Black Belt, MMA Pioneer, 2x ADCC World Champion & Grandson of BJJ Founder

“Back in the early 1990’s, Karel was one of my first training partners in the early days of the Renzo Gracie Academy. We came up the ranks together and now that we are both long time Black Belts, I frequently ask him to visit my school to teach the professional class. I cannot say enough good things about his technique and teaching methods. I highly recommend the book!”

Matt Serra – Former UFC World Champion, Decorated BJJ Black Belt & Renowned MMA Coach

“Karel is one of my favourite training partners. The insights in his book are excellent to learn many techniques for advanced martial artists.”

Georges St. Pierre – 12 time UFC World Champion, one of the greatest MMA fighters of all time & BJJ Black Belt

“I’ve been training with Fox since I was a Blue Belt. His Jiu-Jitsu is pure efficiency and has been an instrumental part of the Tristar Gym curriculum. In his book, he not only teaches a variety of powerful techniques, but he also includes pool workouts/techniques. The pool workouts, in my opinion, hit three birds with one stone. 1st it’s therapeutic, 2nd it increases your fitness level, and 3rd it makes your technique instinctual. Drilling is the key to success, but comes at a price: it taxes the body. Fox has found a brilliant solution.”
